NEEDLE-THREADING DEVICE.

Application filed July 7, 19,7. Serial No. 204,085.

My invention relates to improvements in needle threading devices, and the object of the invention is to devise simple means for quickly and easily passing a thread through the eye of a needle without any hesitation on the part of the operator, and thereby eliminating waste of time which general y takes place, particularly where the operator has defective eye sight, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a perspective view of my device.

Fig. 2 is an enlarged perspective detail of the main operating parts of my device, showing the needle in position.

Fig. 3 is a similar view to Figure 2 with the needle removed.

Fig. 4 is a sectional detail through Figure 2.

Fig. 5 is a detail of the needle receiving recess.

Figs. 6, 7 and 8 are details of the hook 11.

In the drawing like characters of reference indicate corresponding parts in each figure.

1 indicates a base. 2 is a standard bar member extending upward from the base and provided at its upper end with a longitudinally extending needle receiving orifice 3 flared outward annularly at its upper end as indicated at 4 to permit of the easy insertion of the needle.

The bottom of the orifice is formed into a recess 3 having the sides tapered so as to centre any size of needle, the smallest size fitting into the flat bottom of the recess and the larger needle engaging the inclined sides of the recess.

5 is a transverse orifice in proximity to the lower end of the orifice 3 and positioned so that when the needle 6 is inserted through the orifice 3 with the eye end of the needle placed downward, such orifice 5 will be approximately opposite the needle eye 6*. The orifice 5 is countersunk or flared outward as indicated to ensure of suificient clearance for the withdrawal of the hook l1.

7 is a cut-away portion in the face of the standard 2 opposite to the orifice 5 and 8 is a spring finger preferably inserted at its upper end in a saw' cut 8 so that the finger depends into the path of the needle 6 so as to bear thereagainst as indicated in Figure 4. 9 is an arm pivoted at its lower end between the lugs 10 and extending upward behind the orifice 5. 11 is a thread engaging the hook extending from the arm 9 through the orifice 5 and the eye 6" of the needle 6 into the cutaway portion 7 The hook 11 is formed as illustrated in Figures 6 and 7 so as to give as much clearance as possible for the thread as it is drawn through the needle eye.

In order to thread the needle all it is necessary to do is to invert the needle and pass it downward through the orifice 3 until the eye is opposite to the orifice 5 in the position shown in Figure 4, the arm 9, of course, being swung outward from the standard 2 so that the hook 11 is withdrawn.

As soon as the needle has been inserted in the position above described being firmly held in such position by the spring 8, the arm 9 is swung forward in the position against the standard 2 so that the hook mem- 7 her 11 passes through the orifice 5 and the eye 6 of the needle into the cut-away portion so as to project from the needle eye. When in this position a thread is passed by the operator transversely of the cut-away portion 7 so as to engage the hook of the hook member 11. It will of course be understood that in all needles according to common practice the circular periphery of a needle gradually merges into a flattened portion towards the eyed end at opposite sides of the needle and extending past each end of the eye hole. As the needle is inserted in the applicants device the pressure of the spring 8 against the needle at the eyed end when the flat face is turned at an angle to the face of the spring is such that the spring will turn the needle so that the flat face will assume a parallel position to the spring face or and the spring will then bear directly against one of such flattened faces and in consequence will turn the eye of the needle into central alignment with the transverse orifice of the threader so that the thread engaging hook will pass freely through the eye when travelling through the transverse orifice. The arm 9 is then swung outward from the standard and the thread engaged by the hook member is drawn through the eye. When this has been done the needle is drawn upward from the orifice 3, the thread passing upward through such orifice threaded through the eye.

From this description it will be seen that I have devised a simple device whereby a needle may be quickly and easily threaded without any loss of time, and such a device as will enable even a blind person to easily thread the needle if desired.

What I claim as my invention is A needle threading device comprising a bar member, a needle receiving orifice extendlng longitudlnally into one end of the bar member and of less length than the orifice and adjusted to bear at its free end upon the inserted needle, an arm pivotally mounted upon the bar member and extending at its free end over the opposite end of the transverse orifice, a hooked thread engaging member carried by the pivoted arm and adapted to be passed through the transverse orifice and needle eye registering therewith to protrude therefrom and with the protruding end of which a thread is adapted to be engaged to be drawn through the eye as the arm is swung away from the bar member. i
